We study a 3D steady-state thermal model taking into account heat transfer by convection, diffusion and radiation with multiple reflections (grey bodies). This model is a nonlinear integrodifferential system which we solve numerically by a finite element method. Some results of existence and uniqueness of the solution are proved, the numerical analysis is detailed, error estimates are given and two-dimensional numerical results of thermal exchanges under a car bonnet are presented.

<span>Propagation delays and couplings between nearby lines affect the circuit performances (speed, power consumption) and operations. Propagation delays in longer lines can become critical compared to the clock frequency and can induce unwanted signals in neighboring lines ("crosstalk" phenomenon). Induced line capacitances can induce parasitic signals. Hence characterizing of these capacitances is of paramount importance. The present work deals with the analysis of capacitance of a multilayer conductor interconnect aiming for their possible exact extraction. We used three topologies of a microstrip conductor interconnects and identified the potential distributor and then computed the capacitance and inductance matrix using a finite element method. The first analysis dealt with parallel microstrip conductors and the second with two levels (plan) of a microstrip conductors the results are compared to those obtained by other methods and found quite encouraging.</span>
